Step-by-step explanation:

We can find the slope of this line by using two points

(1,-3) and (3,0)

m = (y2-y1)/(x2-x1)

    = (0- -3)/(3 -1)

    = (0+3)/(3-1)

DIRECTIONS: Use this information to answer Parts A and B.
vova2212 [387]

Answer:

The initial weight of the candle is 8 oz.

D.the candle's initial weight

Step-by-step explanation:

  • the weight is 8 oz when time is 0, initial = 0 s
  • the initial value represents the candles initial weight before burning it.

To find rate of change:

\sf \frac{change \ in \ weight}{ time \ taken}

take two points: (0,8),(5,7)

rate:

\rightarrow \sf \frac{y1-y}{x1-x}

\hookrightarrow\sf \sf \frac{7-8}{5-0}

\hookrightarrow\sf-\frac{1}{5}

\hookrightarrow\sf -0.2 is the rate of change.

I need help with this question
AVprozaik [17]

Step-by-step explanation:

Angle formed at the circumference of the circle is half of the angle formed at the center of the same circle.

Hence,

m\angle ADC =  \frac{1}{2} \times  m\angle ABC \\  \\  \therefore \: m\angle ADC =  \frac{1}{2} \times  40 \degree \\  \\ \therefore \:m\angle ADC =  20 \degree  \\  \\

Answer:

the actual pressure is 31.09

Complete question:

What is the actual pressure when Ali's gauge shows 33.58

Step-by-step explanation:

Given,

Ali's tyre presser gauge show a reading 8% higher than the actual pressure.

Ali's gauge shows 33.58.

Let the actual pressure be x.

According to problem,

 x\times\frac{108}{100} =33.58 { [If 8% increasing  of a no ⇒ The number becomes =                      (\frac{100+8}{100})of the number}

x= \frac{33.58\times100}{108}

x=31.09

Therefore, the actual pressure is 31.09
